Induction Bending
Factors:
Heating Speed Bending Temperature
Cooling Speed Mother Pipe Material Properties
Bending Machine:
Air-ringInductorQuench ring
PB450-18”Induction Bending Machine
PB400-16”Induction Bending Machine
Profiles:
All materials that can conduct electricity are bendable, almost regardless of the profile shape!
Induction bending gives you great freedom of choice:• Bending radius: Step-less from 60 mm to 22.000 mm• Bending angle: 0 to 300 degrees• Profile dimensions: max. 300 X 600 mm (width x
height).
Pipe dimensions from 16 mm to 457,2 mm (18”)
Ω – Spool reduced with8 welds and better flow
ExamplesOf cost reducing designs
Ex. 1. Traditional method, with welded standard pipes.6 welded joints
Ex. 2. Induction bends, with long straight ends.1 welded joint
Ex. 3. Induction spool.0 welding
Ex. 4. Induction bends, with long straight ends.2 welded joints
Heating Speed:
Bending Temperature/temperature tolerance
Material Grade Carbon material (870º – 930º)
Duplex / Super Duplex
(1050º – 1120º)
Mother pipe material certificates
Wall thickness
Induction coil
Cooling Speed:
Motherpipe Material Properties
Carbon steel / Stainless steel
Seamless / longitudinal welded
Weld cap (G48)
Segregation / Intermetallic phases in the middle of the plate thickness
Post Bend Heat Treatment (PBHT)
Heating of steel
Capacity: 3,5 tons
Temperature 580°C to 1150°C
Carbon steel - Tempering (SML 360 / 415) - Quenching and Tempering (SML 415 / 450) - Normalizing (SML 360)
Duplex / Superduplex - Wall thickness - Pipe manufacturer - Seamless / Seamwelded - Bending radius
PBHT – Increasing Cost - PBHT - PBHT Batch test - Blasting / Pickling - Single bends = more welds
